BROODEFL' I Specification of Letters Patent.

Patented March 12, 1907.

- Application filed May 17, 1906. Serial No. 317,308.

and exact description as will enable others it appertains toskilled in the art to which make and use the same.

This invention has for its object the ro-'- vision of a brooder which will permit t orough ventilation without undue exposure to the chickens and which will be so constructed that it may be quickly disassembled to ermit cleaning.

t also has for its object the provision of means for accurately adjusting the hoverer to the growth of the chickens.

With these objects in view the invention consists in certain novel features of the apparatus illustrated in the accompanying drawings, as will be hereinafter first fully described and then particularly pointed out in the claims. 1 g

In the drawings, Figure 1 is a vertical section through a brooder embodying my improvements, the hoverer being shown in side elevation. Fig.- 2 is a vertical section of the hoverer and the heating-chamber. Fig. 3 is an enlarged detail view showing the manner of supporting the outerpart of the hovererblanket, and Fig. 4 is a s milar view showing the manner of supporting the central part of the blanket. I

The casing or housing 1 is divided by a longitudinal partition 2- into the brooderchamber 3 and the exercising and feeding chamber 4. The floor of the brooder-cham drawings, itconstitutes a runway over'which' the,chickens may pass from one to the other. chamber. Acloth curtain 8 is hunginr'theopening. or ,doorway to prevent coldair play-r ingndirectly on the" chickens; Above the opening,. 5 the. partitionzis provided withian' opening ;.9','1 j covered by a vscreen 1 0 and in which is. fitted a swinging frame 11, said frame being covered with muslin or other fabric.

Inthe front of the brooder-chamber is an opening 12, having an outwardly-swinging door 13 fitted thereto. This opening is covered within the chamber by a screen 14 and a cloth-covered frame 15, slidably mounted in guides 16 on the inner side of the wall. In the side wall of the exercising-chamber, near the top thereof, is an opening 17, covered'by a screen, and in the walls of both chambers are glazed openings 18. The exercising-chamber is also provided... .witlL-a small door 19, through which the chickens may be permitted to pass into the open air, and also with a large door or skylight 20, through which the condition of the chickens may be observed and through which they may be removed when desired. A removable screen 20 is preferably fitted below this door 20 in order to provide for the thorough ventilation of the chamber. The roof is 1n two parts 21 22, connected by a double-acting hinge 23, so that either chamber may be uncovered without uncovering the other, or the. roof may be entirely removed, as may be desired.

Either member of the roof, it will be readily understood, may be folded over onto the other -member and the roof may 'be' held against slipping by any convenient means, the illustration of which is unnecessa The floor of the brooder-chamber is pro; vided with. an opening 24 atits center, in which is supported a drum 25, having an open screen-covered upper end 26. The drum is not secured to the floor, but rests upon the same by means of an annular bead 27, formed in the drum just above its lower end, as clearly shown in Fig. 2. The drum is thus firmly supported in the proper position, and at the same time it may be readily lifted and removed when necessary for the purupon the screen 26'at the up er end of this drum is a ring 28, having a epending'por tion or riin 29 and an outstanding horizontal.

flange 30, with small hooks or teeth 31 at intervals along the edge of the said flange; A

blanket" 32is engagedflover these hooks or teeth' and is supported bythe same and the flange and -fdepends:i;therefrom to near ithe floor, the outer ied e of the blanket being :turned-rup and'hel r byand between'a depending annular of-the hover-board and a clamping-ring 34. The rim 33 is l crimped, so as to provide an annular groove i 35, and the blanket is carried up over the said groove and is secured therein o y the ring and is drawn tightly thereinto over the which is of a size to fit snugly in the groove l blanket by a belt or similar connection 36, as The free edge i portion of the blanket depends from the ring and is slitted, as indicated at 37, to permit will be readily understood.

extending between the Walls of the chamber,

and is held in the said bar bya nut4l mounted on the rod above the bar. The lower end of the rod is formed into a spider 42, the lower extremities of which are secured to the hover-board whereby the board is supported. At the center of the hover-board is an opening 43, which may be covered by a slide or damper 44, and on the under side of the board is a deflector 45, arranged concen-' trically with the opening 43 and directly over the drum 25. This deflect-or is of an inverted conical form and is provided with a number of openings or perforations 46, through which the heat may be permitted to pass when so desired. It will be readily understood that this deflector serves to turn the heat from its direct upward course and cause it to be spread against the blanket; but

it the damper 4-t be opened the draft will l carry the heat through the deflector and the opening 43 into the breeder-chamber above the hover-board.

Below the floor of the brooder-chamber is a vertical partition 47, dividing the space be low the floor into a heating-chamber and a fresh-air chamber, the fresh-air chamber being provided with an opening or air-inlet 48 in its wall and the partition having an opening 49 in its upper portion for the passage of the fresh air into the heating-chamber. Supported by the vertical partition 47 and the opposite side wall of the brooder is a horizontal partition 50, provided below the heatingdrum 25 with a depressed portion 51 and an upstai'iding flange or collar 52, forming a seat or cup to r'eceiveand support the lower endv of a drum 53, which rises concentrically within the drum 25 and has a closed upper end. .This drum 53 is constructed with a nipple 54 on one side and with an internal partition 55, which extends inward from said side to the center of the drum and then rises therein, terminating short oi" the top clearly shown in Fig. 2. Fitted on the nipple 54 is the inner end of a fume flue or pipe 56, which extends therefrom to and through down tothe lloor and surrounding the the wall of the breeder to carry the fumes 1 from the heater or lamp to the outer air. The

of the drum, as i lamp or heater 57 is fitted in and supported by a horizontal between the bow? and the burner of the lamp, so as to protect the bowl from the heat, and thereby prevent waste of theoil and possible explosions. The partition or support 58 constitutes a removable platform, which may be withdrawn to remove the lamp for cleaning or filling, and the wick-raiser of the lamp is extended to near the end of the said support, so as to be easily reached through a door 100 in the casing or housing in order to adjust the fiame, it being understood that the lamp is lighted and-the flame turned very low before placing the lamp in position. -The air to support combustion may be adlmitted by leaving the door to the lampchamber slightly ajar. Fresh airmay be admitted to the air-flue above the partition 50 through openings 10] in the side of the housing above .the plane of said partition. and this air will be heated through Contact 1 with the flue 56 on its passage to the drum 25. The parts being arranged as described, the lamp is lighted and placed in position and the heatgtherefrom will rise through the ring or colla r 52 and pass into the drum 53, passing up therein and over the top of the partition and then down to the flue 56, through which it will escape into the. outer air. The hot air from the lamp will heat the drum 53 and the flue 56 in its passage through the same,so that the air adjacent thereto will he raised in temperature, and this heated air will pass upward through the drum 25 and escape through the top of the same. As it passes from the drum 25 the heated air will. strike the deflector 45 and Willbe thereby thrown'out'ward and downward against the blanket which. de ends nearly to the floor I of the breeder-c amber and will consei quently apply the heat to the backs of the chickens in the most efficient manner.

I When the blanket gets too hot, the damper 44 is opened'and the hot air will then be permitted to pass upward into the brooderl chamber and raise the temperature of the lsame, so that the chickens may pass out froniunder the blanket and obtain needed l exercise without being chilled. The fumes a from the lamp cannot pass into the brooder I chamber, and as a constant supply of air is l admitted to the fresh-air flue the heated air passinginto the hoverer will be uncontaminated; As the chickens grow-larger the nut.

41 may be manipulated to raise the hoverer and furnish ample space below the blanket for the chickens. At the same time the outer edge of the blanket may be adjusted between the rim 33 and the ring 34, so. that there will always be acurtain extending chickens to keep them warm. By opening the door 13 fresh air may be admitted diartition 58, which extends IOOA rectly to the brooder-chamber and the foul air therein be permitted to escape, so as to effect a thorough ventilation of the same be readily seen that the hoverer can be lifted out through the top of the brooder-chamber after removing the roof and that the drums 25 and 53 may be likewise lifted froni their places, while the flue 56 may be withdrawn through'the side of the brooder. The parts may thus be disassembled in a few minutes i to permit cleaning or repairs.

7 Having thus described my invention, what 1 1 claim, and desire to secure by Letters Pat- I cut, is

1. The combination of the brooder, a support therein, a rod adjustably mounted in said support, a hoverer secured to the lower 1 end of said rod, a damper in the hoverer, a i
